Here's a little explanation about the running lights mod i did on my GTS.
This only goes for GT/GTS models with the "double" indicator bulbs.
What you need is:
*philips screwdriver to remove the indicators and the left knee pad.
*soldering gun or electrical clamps. (the kind you use to connect two electrical wires without cutting them)(don't know the name of those)
*2 leds type T10 with a max diameter of 13mm (0,51 inch)!
*When you remove the left knee pad, i'll find a rather big electrical plug, called the alarm connector. This is normally used for the optional alarm system. We are going to use the white wire of this plug. This wire only provides power when the contact is switched on.
*If you remove the indicator, you see black and white wires. Choose where you want to place the led, in the upper part or the lower part of the indicator.
(i used the lower part)
*Cut the white wire only ! Not the black one!
*Use some extra wire and solder or use electrical clamps to connect both white wires from the left and right indicator.
Then connect this wire to the white wire of the alarm connector under the left knee pad. This wire only gives power when the contact is switched on.
*Test using the leds. (reminding if they do not work, turn them around 180° and try again.
That's it !
